ElasTek Type A & M Test Block Kit

ElasTek Type A & M Test Block Kit (71430-AM)

This kit covers two durometer scales from one set of physical blocks: seven blocks at nominal hardness values of 30 through 90 (in steps of 10), each carrying dual certification for both A-scale and Micro (M-scale) durometers under ASTM D2240. For labs running both instrument types, that dual certification means one kit and one calibration cycle instead of maintaining separate reference sets for each scale.

The blocks are color coded for quick identification, and the full set ships in a latching storage case designed to keep them protected between uses. Individual blocks are available as standalone replacements if a single block in the set needs swapping out rather than the whole kit.

ISO-17025 calibration is included with every kit, and CCSi recommends annual recalibration to keep the reference values current — a service available directly through CCSi. If your lab only runs standard A-scale instruments and doesn’t need the M-scale certification, the Type A kit covers the same seven hardness values at a lower cost.
